Description
We study d-dimensionally compactified non-susy heterotic string models, including interpolating models with the arbitrary number of freely acting Z_2 twisted directions. Taking the limits of the compactified radii to zero and infinity, we show some examples of the various interpolation patterns in the d=2 (8-dimensional) case. In the region where supersymmetry is asymptotically restored, we evaluate the (10-d)-dimensional one-loop cosmological constant. We find out the points in the moduli space where the cosmological constant is exponentially suppressed.
